Decompression Sickness

Decompression sickness is a painful and dangerous condition that is caused by the formation of gas bubble in the bloodstream and body tissue.Another name for decompression sickness is Caisson disease or Bends.Bends takes place when air pressure surrounding the body decreases to fast.Bends is most common among the underwater divers and people who work in construction.Theses people get Bends when they rise to the water surface or to ground level to fast.People in aircrafts may also experience Bends if pressurization does not take place.
The bubbles are formed when air pressure drops to quickly and lets nitrogen that was in the body, comes out of the body solution and forms bubbles.The bubbles are harmful because they stretch or break tissues or impair the circulation of blood through passageways.Some symptoms of Bends are pain in the joints of bones, itching or tingling, breathing problems, and total or partial paralysis.Some less common symptoms are dizziness, nausea, vomiting, convulsions, and coma.In some cases Bends can be fatal.
Increasing the air pressure in a sealed pressure chamber treats bends.In the chamber, the increasing pressure compresses the nitrogen bubbles and causes some nitrogen to go back into solution in body fluids.The pressure slowly lowers so that the nitrogen leaves the body without excessive bubbling.
Bends is a very painful condition.In order to prevent bends, always be careful when diving or moving to different areas of pressure.You don't want bends to happen to you!
